Manifold cooled skating pond spray



Patented May 23, 1939 UNITED STATES PATENT OFFICE 3 Claims.

The object of my invention is to' provide a novel manifold cooled skating pond spray for making skating ponds on vacant lots for the use of children and at very slight cost, and to make it possible to accomplish this result quickly without prolonged waiting for safe ice to form.

y I attain these and other Objects of my invention by the mechanism illustrated in the accompanying drawing, in which Figure 1 is a perspective view of the invention;

Fig. 2 is a detail perspective view of one of the nozzles.

Like numerals designate like parts in each of the views.

Referring to the accompanying drawing, I pro- Vide sled runners l, terminating in upstanding front arms 2 and upstanding rear arms 3, the rear arms 3 being connected by a brace 4 with the hand rail 5 for guiding the device. 1 Braces 6 extend on hand-rail 5 to a pipe 8, and braces 'I extend from pipe 8 to member 3. These are attached by suitable means as by the rivets R. Braces 4, 6 and 'l preferably are integral and may be affixed to rail 5 and pipes 8 by suitable means as by welding W. Pipes 8 are secured to a tee pipe connection 9, which in turn is secured by a coupling ll] to a hose l3 leading to a source of water supply. Afiixed to' tee connection 9 is a hose support ll pivoting in fingers l2. The

water distributing pipes 8 terminate in reducing pipes |4 which have connections |5 engaging them with radiating pipes IS. A plurality of radiating pipes I'I open out of the distributing pipes 8 and tee connection 9, as shown in Fig. 1.

Pipes IS and l'l are affixed to a supporting bar IS in any suitable manner, preferably by Welding W. The bar 19 is supported on the upper end and aflixed to the upstanding front arms 2 of the runners l. Braces 20 are affixed at their 4 y lower ends to arms 2 and at their upper ends to supporting bar IS. The radiating'pipes 16 and l'l terminate in conventional nozzles [8 such as used on garden hose, whereby the nozzle may be adjusted to cause a spray.

The apparatus may be used to produce a skating rink on any park or vacant lot without expensive flo'oding of the site or the throwing up of lumber or banks and without loss of work by the water taking the frost out of the ground and then seeping away. In use the apparatus is pulled or pushed back and forth over the site with a fine spray flowing through the nozzles l8. The spray freezes as it hits the ground and the pond will 5 form very speedily and the ice is perfectly smooth and of course absolutely safe. The machine throws a spray feet wide, which in f'reezing weather will create a large skating rink in 12 hours. There are no air holes in the ice created 10 by this mechanism.

What I claim is:

1. A manifold cooled skating pond spray, comprising a pair of sled runners, a supporting frame connected to the end of said sled runners, a pair 15 of water distributing pipes, means for coupling said distributing pipes to a hose, a series of radiating pipes connected to the water distributing pipes and supported on the framework of the de- Vice, said water distributing pipes having adjust- 20 able spray nozzles.

2. A manifold cooled skating pond spray, comprising a pair of sled runners, a supporting frame connected to the end of said sled runners, a pair of water distributing pipes, means for Coupling 25 said distributing pipes to a hose, a series of radiating pipes connected to the water distributing pipes and supported on the framework of the device, said water distributing pipes having adjustable spray nozzles, a hand-rail for operating 30 the device and braces aflixed to the hand-rail and to other parts of the apparatus.

3. A manifold cooled skating pond spray, comprising a pair of sled runners terminating at each end in upstanding arms, a frame member welded 35 to one of said upstanding arms and functiom'ng as a support for radiating pipes, a pair of water distributing pipes, means for Coupling said distributing pipes to a hose, a multiplicity of radiating pipes connected to the Water distributing 40 pipes and supported on the aforesaid frame member, said water distributing pipes having adjustable spray nozzles, a hand rail for operating the device, and braces welded to the hand rail and to the rear upstanding arms of the runners for bracing the device.
